SIGNAL LANTERN.

Application filed October 8, 1923. Serial No. 667,214.

To all whom t may concern.'

Be it known that I, VILLIAH J. DE-NNING, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Signal Lanterns, of which the following is a specilication.

This invention relates to that class of signal lanterns, carried on the running board of automobiles, and in which a cylindrical shell of colored glass, encloses the electric light bulb, and is held in place between an expanded base member and a superimposed cap member, in a detachable manner, with, a view to removal and replacement of the parts, and the present improvement has for its ob]- ect:

To provide a structural formation and combination of parts whereby the different portions of a signal lantern of the type above mentioned, are connected together' in a substantial manner adapted for rapid disassemblage and separation of parts for repairs, replacements, etc., and a like rapid reassembly of said parts, all as will hereinafter more fully appear.

In the accompanying drawing Fig. l, is a sectional elevation of a signal lantern embodying the preferred form of the invention.

Fig. 2, is a detail vertical section showing a modified formation of the connecting means between the base and cap members of the lantern.

Like reference numerals parts in both views.

As represented in the drawing, the signal lamp comprises an upper member 1 of a cup or dome form, and a base member 2 adapted for attachment to the running board of an automobile and provided with supporting means for an electric light bulb 3, with a cylindrical shell 4 of colored glass, usually red or green, arranged between said cap and base members and enclosing the electric light bulb 3, aforesaid.

Heretofore the connection between the described parts have been by means of a series of vertical bolts arranged exterior of the glass shell 4, which in a dismemberment of the lantern for repairs, replacements, etc., involved considerable time and labor to remove the series of holding nuts from suoli bolts, and a like amount of time and labor in replacing said nuts in a reassembly of the indicate like lantern parts. With a view to materially reduce such loss of time and labor, the present improvement involves a structural formation and association of lantern parts and connections as follows:

A connecting member 5 is arranged in the interior of the glass shell 4 of the lantern, with its upper end passing through the central portion of the cap member l and screw threaded for the reception of a holding cap nut 6. In the preferred form of the invention shown in F ig. 1 the intermediate and lower portion of the connecting member 5 is displaced laterally in order to afford clearance for the electric light bulb 3, and has its lower extremity screw threaded for the reception of a holding nut or head 7 which has bearing on the under side of the central web of the base member 2 aforesaid.

In the modified form of the connecting -member shown in Fig. 2, the intermediate and lower portion 5 of said member is of a forked form with eachI fork passing down through an orifice in the central web of the base member 2 and receiving in individual holding nuts 7 as shown.

With the above described arrangement of parts, it is only necessary to remove the centrally arranged upper cap nut 6, to obtain a separation of the different lantern members, in making repairs, replacements etc. And with a replacement of said cap nut, attain a rapid and substantial connection in a reassembly of the lantern parts.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent, is

1. In a signal lantern of the type described, the combination of a base member, a cap member, an intermediate shell of transparent material, and a connecting member, arranged in the interior of said shell, the upper end of said connecting member passing centrally through the cap member, a removable nut engaging the upper end of the connecting member and bearing centrally upon the cap member, and the lower portion o-f said member having connection with the horizontal web of the base member aforesaid, the aforesaid connecting number and nut constituting the sole means of connection for the lantern parts.

2. In a signal lantern of the type described, the combination of a base member, a cap member, an intermediate shell of transparent material, and a connecting member,

upper end of said connecting member passing centrally through said cap member,v av

removable nut engaging the upper end of the connecting member and bearing centrally upon the cap member, the intermediate aortion of said member being deformed to a ord clearance for the electric light bulb of the lantern, and the lower portion of said member passing through the horizontal web of the base member and having-a holding head engaging beneath said web, the aforesaidy connecting member and nut constituting the sole means of connect-ion for the' lantern parts.

3. In a signal lantern of the type described, the combination of a base member, ar

cap member, an intermediate shell of transparent material, and a connecting member, comprising a singleconnecting bolt arranged in. the interior of said shell with its upper end passing centrally through said cap member, a removable nut engaging the upper end of the connecting member and bearing centrally upon the cap member, the lower portion of said bolt being displaced laterally to afford clearance for the electric light bulb of the lantern and attached to the horizontal web of the aforesaid base member, the aforesaid connecting member and nut constituting the sole means of connection for the lantern parts.

Signed at Chicago, Illinois, this 4th day of October 1923.
